Embodiment 1
[0042] This embodiment provides a quick file packaging method, such as figure 1 and figure 2 shown, including the following steps:
[0043] Create a file packaging format including a file header and a file body;
[0044] The file header includes a format flag for storing the current file format and data storage format, a number flag for storing the number of files saved in the current file package, and a version flag for storing version information; The file body includes at least one file unit, and a file is assembled into a file unit; the file unit includes a unit header and a unit body for storing file content; the unit header includes an isolation flag, an encryption flag bit, a file length flag, a check value and a file name; the file name adopts GBK encoding, which is convenient to encode Chinese characters; the content of the isolation flag is the same as that of the format flag;
[0045] Use the file packing format to pack the files or unpack the packed files.
